Young adults are more familiar with emojis than one of their vehicle's dashboard warning lights, according to a survey by Goodyear Auto Service and Just Tires.

The survey, conducted last fall of more than 1,000 drivers, found young drivers — both millennials and Generation Z — were more than 1.5 times as likely to identify the eye roll emoji or the Wi-Fi symbol correctly than the tire pressure warning light, a spokesman for Goodyear said.

In fact, 49 percent of young drivers and 39 percent of all drivers were unable to recognize the warning light at all, the survey found.

The tire pressure monitoring system light indicates that at least one tire is significantly under-inflated. Possible causes for it illuminating include a puncture, leaking tire because of rim damage and fluctuating temperatures as seasons change, according to Goodyear. Improper tire pressure can lead to uneven tread wear, decreased gas mileage and poor handling.
